安装依赖：
sudo apt-get update -qq && sudo apt-get -y install \
autoconf \
automake \
build-essential \
cmake \
git-core \
libass-dev \
libfreetype6-dev \
libgnutls28-dev \
libmp3lame-dev \
libsdl2-dev \
libtool \
libva-dev \
libvdpau-dev \
libvorbis-dev \
libxcb1-dev \
libxcb-shm0-dev \
libxcb-xfixes0-dev \
meson \
ninja-build \
pkg-config \
texinfo \
wget \
yasm \
zlib1g-dev
Ubuntu 20.04还需要安装：
sudo apt install libunistring-dev libaom-dev libdav1d-dev
FFmpeg为提高编译效率，默认会使用汇编指令，如果没有安装nasm，会导致以下错误：
nasm/yasm not found or too old. Use –disable-x86asm for a crippled build.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file “ffbuild/config.log” produced by configure as this will help
solve the problem.
安装nasm：
sudo apt install nasm
或者也可以在编译时通过添加以下配置项禁用汇编指令编译：
--disable-x86asm
克隆FFmpeg：
git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
进入源码目录：
cd ffmpeg
配置：
./configure --prefix=/usr/local/ffmpeg --enable-openssl
常用配置项还有：
--enable-gpl \
--enable-gnutls \
--enable-libaom \
--enable-libass \
--enable-libfdk-aac \
--enable-libfreetype \
--enable-libmp3lame \
--enable-libopus \
--enable-libsvtav1 \
--enable-libdav1d \
--enable-libvorbis \
--enable-libvpx \
--enable-libx264 \
--enable-libx265 \
编译安装：
make && make install
添加环境变量：
vi /etc/profile
在末尾添加如下行：
export PATH=$PATH:/usr/local/ffmpeg/bin
载入环境变量：
source /etc/profile
